What is the US Government preparing for?

The US Government Has Ordered Over 750 Million Rounds of .40 Caliber Hollow Point Ammunition

Multiple government agencies that specifically operate primary inside the United States have gone on a literal ammunition spending spree in preparation for what they must believe will be some sort of violent event.

The Department of Homeland Security is not the only US agency openly stocking up on .40 caliber ammo.

In November 2011 the FBI posted a request to the FBO.gov website for up to 100,000,000 rounds of hollow point ammunition.
